Specification of Letters Patent.

Application filed June 4, 1907. Serial No. 377,186.

Patented Aug. 4, 190 8.

and consists in certain novel constructions and combinations of parts as will be hereinaiter described and claimed.

In the drawings, Figure 1 is a front elevation of a heater embodying my invention. Fig. 2 is a side view thereof. Fig. 3 is a vertical longitudinal section on about line 3-3 of Fig. 2. Fig. 4 is a cross section on about line 4% of Fi 3. Fig. 5 is a detail cro section drawn through the water tank. Fig. 6 is a detail vertical section illustrating the tubes for connecting the water tank with the annular water spaces below the same.

In carrying out my invention, I employ a suitable casing A, which m. be of any suitable metal, and may be nic :eled, japanned, enameled, or otherwise finished and ornamented to suit the trade. This casing A has a bottom lining A, a side lining A, and a top lining A of asbestos or other suitable nonconducting material, in order to insulate the contents of the casing, and prevent waste of heat.

At its bottom, the casing has a central tire hole A*, and at its to it has outlets A and it is also provided witn suitable openings for the passage of the pipes leading to and from the interior of the ca: as more fully described hereinafter.

A burner B operating in the tire hole A may be supplied with any suitable fuel through a pi e B having a valve B and shown as leading from a tank B mounted on the casing A for the reception of gasolene or other suitable fuel. Within the case at the top thereof, and preferably immediately below the lining A I provide awater pan C, having a central depending, preferably tapered, tubular extension C which extends down to 'a point near the bottom of the cas ing and rests immediately above the fire hole A and communicates at its lower end by latchamber D which communicates at its lower end through a cross gsis age. D with an outer annular water space E being interposed between the water chamber D -and the central flue, and an annular pipe space E being interposed between the inner and outer annular water chambers, as will be understood from Figs. 3 and 4 of the drawings. The inner fire space E communicates at its lower end with the fire hole A,

and at its upper end through a passa e E" with the outer fire space E, and a cylindrical plate or ilange C depends from the water pan 1n the outer fire space E to a point near the lower end of said fire space E, and operates as a baflle to divide the said space E so that the heat delivered to said s ace through the cross space will be caused to pass down at the inner side of the space E and then up at the outer side thereof, where it delivers throu h a cross )ace E to a side space E extending alongsi e the tank C and dlscharging through the openings A as will be understood from Fig. 3 of the drawing.

The inner annular water chamber D conmeets at its upper end with the pan C, by means of short tubes (1, as shown in Figs. 5 and 6, and short tubes (i connect the upper end of the outer annular water chamber D with the said water pan, the pan being thus supported on the tubes (1, (Z and on its central dependin tube C before described.

in the operation of the described construction, the heat from the burner B will circulate up through the inner heating space E surrounding the tube C, thence across at E, and down along the inner side of the depending battle plate C and then up along the outer side of said plate, and thence along the bottom and sides of the pan C, and out at A,

so that nearly all the heat units will be extracted before the products from the burner are discharged at A, as will be understood from the drawings, referringespeci ally to Figs. 3 and 4.

A soot valve E connects with the hot air space to permit the removal of accumulated soot whenever necessary, and a drain valve 1) connects with the water chamber for emptying the heater whenever desired.

By the described construction, it will be noticed I provide the heater with a central dongitudinal heating flue E, and a pair of concentric annular water chambers D and eral tubes C with an inner annular water D surrounding said flue, and spaced apart by an intermediate iluc, the said water chambers being connected at their lower ends at D, and a water pan C being arranged over the water chambers and provided with a central depending extension or tube projecting down within the central flue and with a central plate or flange depending from the said water pan in the hot air space between the .inner and outer water chambers and forming a partition or deflector for causing the heat to circulate from the central flue down and then up between the inner and outer water chambers as before described.

A dead air space A is provided between the outer water chamber D and the insulating lining, and longitudinal ribs A on the outer side of the water chambersee Fig. 4 divide the said dead air space and operate to space the inner parts of the heater properly away from the insulating lining in such manner as to secure the dead air space at all sides.

In supplying water to the heater, I provide a supply pipe F having an inlet at F in a suitable T coupling and adapted to receive any suitable water connection, and on opposite sides of the inlet I provide valves F and F, the latter controlling the supply connection at F with the lower end of the tank, and the former valve F controlling the connection at F with a discharge pipe G which extends down from the top of the heater and has a lower discharge end G braced in connection with the heater by a strap brace G the said pipe G having at its upper end a cross pipe G connecting through a suitable T couplin G, with the top of the hot water pan, and laving an upwardly extending connection G5 controlled by a valve G and adapted to 0pcrate as a vent, or for top transmission of hot water as may be desired. By this construction it will be noticed that by closing the valve F hot water may be delivered from the pipe G, or if the water is too hot, the valve F may be partially opened in order to secure the desired temperature. It will also be noticed that the valve F maybe manipulated to secure the discharge of water from the pipe G when the inlet is suitablycoimled up with any desired water surface.

The hanger shown in Figs. 2 and 4, is employed in securing the heater to the wall. This hanger has a main .bar or upright H whose lower end is bent forwardly at H to underlie the heater. To this main bar are secured upper and lower cross bars forming laterally extending arms H and H which extend alongside of and are riveted at 71.2, h to the heater. to the upper end of the main bar and to the cross bar H and has an opening to fit over a nail. This hanger when arranged as shown in Figs. 2 and 4 will operate to securely support the heater.
